Tire tread



FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that the pattern repeats uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a right side elevational view thereof, the other side being a mirror image thereof; and,

FIG. 4 is a enlarged fragmentary front elevational view thereof.

In the drawings, the broken line showing of a sidewall, inner bead, and peripheral boundary between the tire and sidewall depicts environmental subject matter and forms no part of the claim. 

The ornamental design for a tire tread, as shown and described.
